Abstract
In the design process multiple drawing a long axially symmetric continuous and composite products at the stage of rough drawing it is advisable to use drawing tools with the channel of two cones, in which input cone ensures a low compression and improved conditions of friction compared with standard drawing tools, and the compression occurs in the second cone of the working part of the channel drawing tool. The formulas for calcu- lating the pressure of drawing axisymmetric drawing products and optimum geometry of the channel drawing tool with the channel of the two cones. It is shown that the drawing tool with the channel of the two cones at the expense of improvement of conditions of friction can reduce pressure of drawing and, accordingly, to provide the best power parameters of the process of drawing, reduce the filament and the defectiveness of a work piece, which is specially important in the process of drawing composite products.
